Hot restart a Tyk Gateway Process

It is possible to hot-restart a Tyk Gateway process without dropping any connections, this can be useful if you need to load up a new configuration or change a configuration on a production server without losing any traffic.

To hot-restart a Tyk Gateway process, you simply need to send a SIGUSR2 signal to the process, for example:

> sudo kill -SIGUSR2 {gateway-pid}

This will fork and load a new process, passing all open handles to the new server and wait to drain the old ones.
